for Cinema 4D I’m not sure if the renderer uses the GPU, if yes you should need a decent GPU, too = very good performance in both programs is impossible for the money.

What program do you use more?

C4D is like ae, use CPU for final render and GPU for fast viewport and preview. All components are important and should be balanced.

afaik AE makes almost no use of the GPU unless you have a plugin that makes use of it. The ram-preview is calculated by the cpu, and the opengl fast-preview should be off as it is slower than adaptive resolution. I don’t know about Adobe CC, but at least in CS6 I can work on my laptop without proper GPU as fast as the CPU can handle it.

You should go with an intel i5 or i7 CPU, preferably combatible with 1155 socket to gain some money. A motherboard with SATA 3 support and an SSD drive.
And 16 or 32GB of Ram.
These will be a serious upgrade but the budget does not allow an investment to a graphics card. I would use an old one and i would replace it later.

Power supply: Enermax Revolution87+ 750W, ATX12V v2.3, ERV750AWT-G (one of the best and very silent)

Memory: Kit Dual Channel Kingston 16GB (2 x 8192MB), DDR3, 1600MHz

Primary Hard Drive: SSD Kingston HyperX 3K 2.5, 120GB, SATA 3

Secondary Hard Drive: HDD WD Blue, 1TB, 64MB, 7200rpm, SATA 3

Video Card: MSI GeForce GTX 770 Lightning

This is my configuration and is working great. I recommended you. But if you want to save more money you can do this from Enermax Revolution87+ 750W, ATX12V v2.3, ERV750AWT-G or Cooler Master Silencio 650 if you don’t interests you the silence very much. And from the MSI GeForce GTX 770 Lightning also you can get GTX 760 and get more cheap. For other information please tell me. I didn’t send you link with this components because i don’t know from where you buy it.
